CHARLES A. RANDALL, OF NEW YORK,N. Y.

IMPROVEMENT m PE liFORATING APPARATUS FOdELECTfiIC TELEGRAPHS.

- Specification formingpart of Letters Patent No. d93,$72. dated July 31, 1877 application filed l v November 15, 1876.

To all whom it may concern Be it known that I, CHARLES A. RANDALL, of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Perforating Apparatus for Electric Telegraphs, of which the following is a specification have the perforations representing the letters to be arranged relatively and corresponding to the same letters on the type-circuit wheel of the receiving-instrument; and my invention is designed to furnish a convenient handinstrument, by means of which the proper perforations may be accurately'and rapidly formed by hand.

My invention consists in a drum orroller mounted on a suitable journal and provided with suitable gearing, by which it may be rotated. Said drum is of the same diameter as the type-circuit wheel, or type-wheel, in the receiving apparatus, and is provided upon its front face with an alphabet, the letters of which correspond exactly in position with the letters of the alphabet of the type-wheel of the receiving instrument. This drum or wheel is adapted to carry the strip to be perforated, and the shaft on which it revolves is provided with a pointer or finger, which indicates when the wheel is in proper position for the perforation of an aperture corresponding to a particular letter. Above said drum is arranged a perforating-punch, through which the strip of paper is carried .by the action of the drum, and which can, at proper intervals, be operated to cut through the paper.

In the drawing, Figure l is a front elevation of my improved perforating apparatus. Fig. 2 is an end view Fig. 3, view of a modification thereof.

In the drawing, the letter A represents a rectangular standard, mounted upon a suitaproper position for the perforation corresponding to any particular letter. To the rear face of the drum is secured a gear-wheel, F, and a ratchet-wheel, G, and pawl H, the gear-wheel meshing with a driving-wheel, I, by which the drum maybe put in motion, the ratchet wheel and pawl causing the drum to be arrested with the center of the letter which the pointer designates directly opposite the pointer.

M represents a spring, secured to the upright standard, for throwing the pawl into the ratchet-teeth. The letter N represents a friction-wheel, mounted upon one end of a rod,

0, pivoted to the upright standard, which is caused to bear upon the paper upon the drum by means of a spring, E, and cause it to travel with the drum. The letter S represents the punching device, which is secured to the upper end of the vertical standard, and is provided at its front end with a punch, T, and cutting-die U, the paper being carried between the upper face of the die and the punch in a recess formed between the die-plate and the lower face of the support which carries the die and punch, the ends of the paper passing down through guides at each side of the same.

In the modification shown in Fig. 3 the dieplate is dispensed with, and the periphery of the wheel, at proper intervals, is perforated, each perforation, in conjunction with the punch, operating as a cuttingdlie for its particular perforation.

The drum may be covered with copper or rawhide, if desired, for the reception of the end of the punch, and the punch may be operated by means of a suitable lever, instead of directly by hand.

Theoperation of myinvention will be readily understood from the foregoing description.

The paper being in proper position, the drum is rotated in the proper direction, so as to bring the proper letters successively in line with the pointer, and the paper is perforated by astroke upon the punch, and, as the letters are all relatively placed to correspond with those of the type-wheel of the receiving instrument, it is evident that the perforations will be made with the utmost accuracy.

Instead of arranging the letters on the face of the drum, they may be arrangedin alarger circle upon a separate support, so as to be more distinct, with the pointer aifixed to the drum or its shaft, and rotating therewith.

What I claim, and desire to secure by Letters Patent, is-- 1. In combination with a fillet of paper or other non-conducting substance, the rotating paper-feed drum 0, of the same diameter as the type-circuit wheel of the receiving apparatus, and the punch S T and die U, the whole arranged substantially as described.

2. The combination, with a fillet of paper or other non-conducting substance, of the paperfeed drum 0, rotated by the movement of the fillet of paper and constructed of the same diameteras the type-circuit wheel of the receiving apparatus, and the punch T and die U, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of the subscribing witnesses.
